鱼群声纳探测装置的设计

Design of Sonar System for Fish School Detection

介绍研制的渔用声纳探测装置。该装置由超声波功率发生器、超声波接收等硬件电路组成,信号处理由单片机C语言编程实现。在实验室模拟水中环境对装置进行了实验,实验数据表明:该装置的测试范围、精度均达到了设计要求。

This paper introduces the principle of fishing sonar, and describes the design of a sonar system for detecting fish school, which can be used to increase the yield of marine products.The sonar consists of an ultrasonic transmitter and a receiver which include circuitry for amplification, comparison, alarming, etc. The software programmed with C language is responsible for distance calculation. Laboratory tests have been carried out to simulate the ocean environment. Experiments show that the detection range and accuracy can meet practical requirements.
